Question # 1 / 17

In quantum mechanics an unlocalized electron moving in a flat 1D world of length L is represented by the plane wave:

where is the wave radial frequency and k the wave vector.
Identify the following quantities:
average electron momentum average electron energy electron probability-density of presence at x uncertainty on the momentum uncertainty on the position
average electron momentum average electron energy electron probability-density of presence at x uncertainty on the momentum uncertainty on the position
average electron momentum average electron energy electron probability-density of presence at x uncertainty on the momentum uncertainty on the position 1/L
average electron momentum average electron energy electron probability-density of presence at x uncertainty on the momentum uncertainty on the position 0
average electron momentum average electron energy electron probability-density of presence at x uncertainty on the momentum uncertainty on the position ~L

In Quantum mechanic the amplitude square of the wave function gives the probability-density of presence at time t at position x.
